I have wanted to try playing a mage but I have a very hard time with it because they seem so less effective than my warrior classes in the past. I primarily used Heavy Armor, Shield, Sword and of course maxed smithing. My character was insanely powerful and I found enemy mages to be the easiest to kill. With my elemental protection I shrugged off the half of their attacks, combined with the Lord stone it was even more unfair for them. I never had to worry about running out of stamina because I did a lot of basic attacks and didnt go bashing everything under the sun. Between my armor and my shield I rarely ever needed to heal and just as an added benefit I used Become Ethereal if I was about to get nuked.
My problem is that every attempt I have made at a mage feels so lack luster. His damage is ok sure but he has terrible defense even with Oakflesh. Conjuration seems like a nice distraction tool but my summons die quickly. I think the biggest issue overall is that my magic drains insanely fast in anything above a skirmish. I have points in destruction and the first couple of perks for Novice and Apprentice perks, additionally I put everything into magicka when I level and am wearing fancy robes.
At the end of the day I just dont see the point of playing as a mage except for roleplaying sense. I would love to hear from those who have mastered being a mage to hear what they do to make the style work, suggestions to make myself a better mage, and anything else that you might find helpful. Sorry about the long post.
